some time ago my improved construction was used to replace a builtup body bolster arrangement the improved bolster on tank cars in service, and

which had failed has been tested in service and found practical and very satisfactory.

Some of the objects of the invention are:

(1) To provide a body bolst porting rigidly connecting er bracket for supthe tank of a tank car and means for same to the center sill.

(2) A tie plate rigidly connecting the bottoms of the body bolster brackets and the center sill and provided with an integral body center plate.

It will be noted in the drawings that the center sills 5 may be of conventional construction, or a reinforced construction as shown, formed of channel irons 6 connected at the top by means of a top plate 7 and at the bottom by a plate 8.

In accordance with my invention, I arrange at each side of the sill, a bracket 9 preferably consisting of a single web 10 from which projects ing flanges 11, 12, 13, 14 and be apertured as shown at 16 weight, and beads 18 metal casting having a center oppositely extend- 15.

For increasing the strength of the structure, the bracket has another projecting flange 23 extending over a portion of the plate '7, so that the flange 23, plate '7 and the center sill may be rigidly connected by rivets or the like 24.

In order that the flange 12 may conform to the surface of the tank, such flange is of arcuate shape, and the usual arranged between the body bolster and the tank, may be secured to this flange by bolts or the like, which pass through the holes 25 of the flange.

A walk 26 may be supported by the flange 13, and the latter has apertures 27 to accommodate boards (not shown) that are boltsor the like employed to secure the walk in position.

One end ofa tank strap is shown at 28, and this is anchored by passing through a sleeve 29 integral with the flange 13. A hole30 in the web of the bracket permits manipulation of the nut 31 that anchors the strap in-position.

Reinforcing ribs 32,33, 34, 35 and 36 strengthen the flanges 15 and 14, and the former provides a side bearing 3'7 which is riveted to a wearing plate 38 that cooperates with the side bearing 39 of a truck bolster 40, which may be of conventional design. Another rib 40a joins the parts 14 and 3'7 and reinforces the bracket.

I preferably combine with this improved form of bracket, a tie plate 46 that is rigidly connected;
